...speed. If you do not have enough torque, then the issue is probably with one of the main IC's (IC101, IC102, or IC201) - however, it could be any of the other circuits as well. A qualified ...
...IC101 is a positive 15 volt regulator and IC102 is a negative 15 volt regulator. More often than not, it is the negative regulator that has gone bad. Reason 3 The amplifier circuit has a 10 ohm ...
...resistor and it checked out @10.7 so that looks OK. The DC voltages for R 145 and R146 look way out of wack. When measured against chassis ground R146 read -28.49 on one side and +3.28v on the other. ...
...ideas would be helpful. R388 & R385 input +15 v out 7.5 v 27ohm x 2 .7.5v for tuner sys go to IC101 and IC 102....use oscillograph check all signal check ic302.... check Q512 2SD2144STA ...
